[kde-community] Changes to mailing list behaviour

[Ben Cooksley]

Hi all,

Just a heads up on an upcoming change.

As mentioned in an earlier thread, we'll need to change a series of
settings on our mailing lists in order to maximise compatibility with
mail providers which have enabled DMARC for their domains.

Any changes the mailing list makes to an email, such as to the
subject, mail body or certain headers (which varies from provider to
provider) can cause breakage of DKIM signatures, and therefore a DMARC
validation failure.

Validation failures can result in messages being bounced or bulk
(spam) foldered by recipients of messages, and likely harms the
reputation of KDE.org mail infrastructure as well (impacting
deliverability for all email). By altering messages and causing these
failures, we effectively exclude people from our community simply
because of decisions taken by their mail provider.

We'll therefore be disabling stripping of any attachments or html
bodies, modification of mail subjects, and removing any mail headers
or footers which the list is adding into any mails. This will be made
globally across all lists on kde.org infrastructure some time in the
next week or two.

Regards,
Ben
